To all 7.0/1.0! it may concern:

Be it known that I, Janus T. DOWDALL, a. citizen of the United States ofAmerica, residing at WVoodhaven, Queens county, New York State, haveinvented certain new and useful Improvements in Spool-Supports, of whichthe fOllOWlllg is a full, clear, and exact description.

This invention relates to spool-holders forsewing machines. My inventionis directed toward the provision of an efficient support for spools ofthread, such are-used for inamlfacturing garments or the like in large(1I'l2t1ll3llJlGS. Sewing thread for the above named purpose is suppliedin the form of large spools or cops in the form of a coni-- cal spool.It is quite essential that thread for machines which are operated athigh speed should be reeled off the spools or cops easily and withoutdanger of catching. My

improved holder is designed to stand upon 7 or be supported over thetable of a sewing machine and may be placed in a position best sulted toobtaln good results. 3

A further object of the invention is to provide a holder that can beadjusted to spools or cops of various sizes, and also one that can becheaply manufactured.

Other features of improvement will be pointed out in the followingspecification and illustrated in the accompanying draw ing. wherein:-

Figure 1 is a side elevation of my improved spool holder;

Fig. 2 is an enlarged cross-sectional view taken on a line 22 in Fig. 1;

Fig. 3 is a diagrammatic detail view illustrating the manner ofsupporting a spool of thread;

Fig. 4 is a similar view illustrating the manner of supporting a 001) orconical spool of thread; and

Fig. 5 is a fragmentary side elevation of a modified 'lorl'n of holder.

As herein embodied my invention comprises a block or body member 6 towhich the spool or cop engaging arms or members are connected. Thespool. or cop engaging arms are indicated by 7 and 8 and are se cured atone end thereof, to angle members or frames 9 and 10, respectively, theframe members 9 and 10 being engaged by a rotatable operating spindle 11provided with righthand threads 12, and left-hand threads 7 1,3 engagingthreaded openings 141 and 15,

respectively, in the frames 10 and 9, respectively. The spindle 11 isrotated by means i of a handle 16, and will, when rotated, cause thearms 7 and 8 to approach or recede one from the other, a pin 17 beingutilized to Fig. 3, or a conical cop indicated by 19,65

Fig. 4.

To rotatably support the spindle 11 and also to prevent longitudinalmovement thereof, I provide the same, intermediate its ends, with anannular recess 20 (Fig. 2)

which is engaged by a tap-bolt 21. The tapbolt prevents the spindle frompremature removal from the block 6 and at the same time permits thespindle to be rotated.

To grip the core of the spool or cop, I provide the outer end of eacharm 7 and 8 with a tooth 22 sharpenough to engage or slightly enter thecore of the spool or cop.

In combination with the spool 01' cop holder, I provide a thread guide23 having an eve 2 1 alining with the axis of the block 6. The threadguide is adj ustably supported by a post 25 carried by the block 6 ofthe spool or cop-holdcr, a set screw 26 serving to maintain the guide 23in adjusted p0- sitions. The holder and thread-guide are supported by astandard (in this instance) indicated by'27, said standard beingprovided with a base 28 to enable it to be maintained upon a table of asewing machine in an upright position relative to the machine proper.

The frame members 9 and 10 not only support the arms 7 and 8, but alsoserve to act as a backing for a spool or cop, particularly a cop asillustrated in Fig. 4:.

As the core of these cops is tapered it would be diflicult to supportthem in a hori zontal position,-a osition which isdesirable for theunreeling of the thre'ad,un-

less some means is used to maintain them in said position while the armsor clamping members are being adjusted or applied thereto.

To mount a spool or cop it is but necessary to operate the s indle 11 tocause the arms orclamps 7 anc 8 to come together, after which the spoolor cop is placed over the maintenance of said position.

said arms or clamps and forced against the frames 9 and 10, asillustrated in Fi 4. The frames 9 and 10 form the base of the clamp as awhole, and the axes of the arms 9 and 10 are located at a right angle tothat portion of said frames against which the spool or cop is forced;hence after the spindle 11 is operatedv to move the arms 7 and 8 apartto gripthe core of the spool or cop, the said spool or cop will bemaintained in a horizontal position, the backing provided by the frames9 and 10 serving to aid in the By means of the above arrangement, theaxis of the spool or cop will be maintained in line with the axis of theblock' 6.

1 The above described arrangement of parts is particularly well adaptedfor cops or conical spools of thread. Instead of providing two movablearms I may provide thebloek 6 with a fixed arm 29 Fig. 5 and an arm 30of angular frame members, a support therefor, a threaded spindlerotatably mounted on said support and engaging said frames,

dle in threaded engagement with the said frames and arranged to causethe arms thereon to approach or recedeonefrom the other, and aguide-pinin slidable engagement with the angular-frames.

3. A spool-holder comprising a support, a

block, angular frames movably associated therewith, spool-engaging armsprojecting from the frames, a rotatable operatingspindle in threadedengagement with the said frames and arranged to cause the arms thereonto approach or recede one from the other,- a guide-pin in slidableengagement with the angular-frames, and means tollock the spindleagainst longitudinal movement. Signed at New York city, N. Y., this 11thday of September, 1918.
